The object of my present invention is to devisea novel construction of a combination vide,

f It further range wherein the same baking oven can be employed for cooking W1th a solid fuel, or with gas. 0 p

A further object of the invention is to devise novel means for mounting a burner in the bottom of the oven and novel means for providing the proper air for combustion. A further object of the inventlon is to proin a device ofthis character, novelventilating means whereby the proper ventilation of the baking or cooking chamber can be maintained. i

With the above and otherobjects in view, i i ploy, 1n con unct1on with a-range adapted forburmng solid fuel, a gas burnerwhich as willfhereinafter more clearly appear, my invention comprehends a novel comblnation range. l comprehends a novel combination range wherein a common baking and heating oven is provided whlch 1s adapted to beheated by the products of combustion passing from a fire or solid fuel, such as, for

- example, coal, wood, orcoke, and also by means of a novel construction and arrangement of a gas burner mounted onthe bottom plate of the oven. a

Other novel features of construction and advantage will hereinafter clearly appear in the detailed description and the appended claims. w v

For the purpose of illustrating the invention, I have shown in the accompanyingdrawings a typical embodiment of t, wh ch, in practice, will give satisfactory and reliable results. It is, however, to be understood that the various instrumentalities of which my invention consists; can be variously arranged W 0 and organized, and my invention is .not limited to the exact arrangement and organization of these instrumentalities as herein set forth. 1

Referring to the drawings My present invention enables one to cmner in order toprovide for its ease of assem'- bly, and durability, and also to providethe requisite airfor combustion, as well as the proper ventilation of the oven when gas is l designates a combination ing my invention, which is provided. with a baking and cooking oven 2. AThis baking and cooking oven 2 is adapted to be heated by means of the products of combustion passing from a coal, wood, coke, or equivalent fire 3, 1n the dlrection of the arrows, passing range embodyoverthe topof the oven through the passage 4 around the side of the oven through the passage 5 and across the bottomof the oven through the passage 6. The'products of combustion then passthrough the port Tinto the discharge passage formed by the flue 8.

The products of combustion maypass directly fromthe fire to the flue 8 if the manually actuated damper 9 is in its open position to permit the air to pass through the conventional ports opening into the flue 8. -10des1gnates a valve controlled gas conduit WhlCll. communicates W1th a gas burner 11 which is mounted within an open-ended casing 12. The bottom 13 of the oven is provided witha shoulder forming step 14 adapted to receive'a casting 15 in theform of an annulus. This castinglo is seated at its outer portion on the step 14 and at its inner portion on a shoulder forming step 16 connected with a plate 17 in the form of a casting. An asbestos ring 18 is interposed between the ring shaped casting 15 and the steps on which it is supported. The casting 15 is flush with the top face of the bottom plate 13 of the oven and is secured by means of fastening devices 19 with an auxiliary bottom plate 20 spaced from the bottom plate 13 and adapted to be received in the recess 21 in the casing 12.

The ring formed by the casting 15 is secured to the plate 17 by means of fastening devices 22, such as, for example, the stove bolts and nuts shown. The burner 11 is supported by means of a bar or plate 23 on which the burner 11 rests and this supporting member 23 is mounted on the threaded rods 24 which are provided with nuts 25 which retain the supporting member @23 against the spacing members 26 so that an air passage 27 is provided for the burner. The casing 12 forms a combustion chamber and is recessed at its upper end as at 28 to receive the depending portion of the plate 17 which is centrally apertured as at 29. The plate is providedwith a depressed seat 30 formed by an annular recess adapted to receive a cover 31 which is hinged to a bracket 32 hinged at 33 to the plate 17. The plate 17 is provided with the vent ports 34, preferably located on opposite sides of the passage 29. The air for combustion enters through the ports 35 in the back wall of the range.

The oven is provided with a ventilating damper 37 mounted in guides 38 and provided with ports 39 which control communication with the exit flue 8. This damper is manually controlled by means of a grasping handle 40 connected with the slide damper 37 to move it into its opened or closed position. This damper and the ports which it controls is preferably located in the inner and upper left hand corner of the oven so that a direct communication can be made with the exit flue 8.

The upper part of the range is provided with the gas heated top 41, the necessary gas burners being provided therefor, and it is also provided with the coal heated top 42.

The manner in which the combination range is operated and controlled will now be apparent to those skilled in this art. Any desired type of solid fuel may be placed on the grates 36, and if the slide damper 9 is in its opened position, the products of combustion will pass to the exit flue 8. If, however, the damper is closed then the products of combustion pass around the oven passing through the port 7 into the exit flue 8. If it is desired to employ, in addition to the heat derived from the coal fire, heat from a gas burner, the cover or lid 31, which was before in its closed position, is now moved into its opened position, seen in Figures 3 and 4, and

the gas burner 11 is lighted so that the common oven 2 is both externally and internally heated. When the portion of the range, adapted for solid fuel, is not being used, such as, for example, would occur in warm Weather, the gas burner only is employed. The air .for combustion enters through the air inlet ports 35 and passes through the passages 27 to the burner 11, thence through the outlet 29 of the casing 12.

' lVhen the oven is to'be heated by gas the cover 31 is moved to uncover the aperture 29 and also the vent ports 34. The ventilating dan per-37 is openedfor a short period and then it is closed so that the oven is vented by the products of combustion passing through the vent ports 34 into the bottom passage 6 and thence through the port 7 into the discharge passage formed by the flue 8. When the stove is heated by solid fuel the usual draft door is employed for admitting air for primary combustion, and the cover 31 is closed thus closing the vent ports 34 so that the venting action takes place through the main ventilating ports controlled by the damper 37. If the range is used for burning only solid fuel, then the cover or lid 31is closed on its seat 30.

My present construction and arrangement of gas burner in the bottom of the oven is constructed and arranged in such a manner that it can be economically manufactured and assembled and will not interfere with the operation of the range when solid fuel is being used.

t is also constructed in such amanner that the buckling of the bot-tom ofthe oven is prevented.

It will now be apparent that I have devised a new and useful combination range which embodies the features of advantage enumerated as desirable in the statement of the in vention and the above description,.and while I have, in the present instance, shown and described a preferred embodiment thereof which will give in practice satisfactory and reliable results, it is to be understood that this embodiment is susceptible of modification in ivarious particulars without departing from the spirit or scope of the invention or sacrificing any of its advantages.
